- The invention relates to an installation intended for the dry-cooling t incandescent coke. I

To this endat least onecontainer receiving the coke to be cooled isrun into a chamber arranged on the floor level of the installation, the walls of the chamber beinglined with hollow bodies, through which a cooling medium flows and which are connected to a heat exchanger.

The hollow bodies may be designed as tubes and connected to. a boiler drum arranged above them and acting as a heatstorage member. In larger installations of this type, it is of advantage to subdivide the chamber intended to receive the incandescent coke,

into two or more compartments which are separated from one another by heat exchanging tubes. Spaces may be left free between the tubes, the side walls of thecham- Figure 1 is anelevation of the installation designed in accordance with my invention, partly in section.

a Figure 2 is a section on line IIII of Figure 1, and

Figure'3 is a sectional view, similar to that of Figure 2,of a modified form of the in-' stallation. 7

Referring now to thesedrawings, a denotes the oven battery of a gasworks, from which battery the incandescent cokeis suppliedto "the cooling plant working onthe dry process, .by means of containers 6 running on rails 0.

I r This cooling installation consists of acham- I ber (2 adapted to be closed onall sides. The

coke containers 6 may be run into this chamher without beingraised or loweredby any lifting device. The side walls of the cham ber d are lined withwater tubes 6. The tubes 6, together with a boiler drum i, joined to them above and a collector g joined to them 234,626, and in Switzerland November 22, 1928.

below, form a sort of vertical water tube boiler. ,f

The installation operates in the following manner: 1 I f f The incandescentcoke delivered tromthe u coke ovens is run by means'ot' the containers 6 into thechamber chatter the door h of the latter'has been opened. The'door h is then I closed andthe c'oke remains in chamber all until it has sufliciently" cooled down. sensible heat of the cokeis thereby transmitted to thecontents of the boiler, principal-L lyby radiation, which contents,.according to Y the conditions prevailing,-are either brought to a higher temperature or evaporated. After the coke has cooled down to about the boiler temperature. the opposite door '2' is opened and the coke is withdrawn from the coolingchamber d in the same containers bin I which it has beeniintroduced,this being et tected by running the container 2) on the prolongation k of the track 0.

The tubes 6 are arranged at. a certain distance away from the side wallsot the .chame ber (Z, to enable a circulation of the gaseous 175 contents'of the latter in-the direction of the arrows, Figure 2,-whereby the heatrtransmission'is favored. To this latter end, suitable directing walls'or other baffle means may, further be provided between the tubes 6.

Figure 3 illustrates a somewhat modified coolinginstallation according to my invention, comprising two coke containers arranged beside one another; in this installation water tubes are provided also between .85

the two coke containers. By charging the two compartments of achamber of this type alternately, the heat transfer to the boiler is rendered'more uniform. Instead of two compartments, as illustrated, a plurality of them may of course be provided. In trans- 'mitting heat to the boiler the .water tubes located in the vicinity of the doors act as down tubes,whilstthe other tubes act'as risers, a satisfactory water circulation thus being ensured. v

The coke containers 6 are equipped with rollers m enabling .them to travel on their trucks Z, so, that the containers may bepushed into the cooling chamber without the trucks]. gees UNITED stares onset; i

Thew

The latter are thus protected as far as possible from the noxious action of the heat.

What I claim and desire to secure by Letters Patent, is

1. An installation for the dry cooling of incandescent coke and the like comprising a chamber, a boiler comprising a lower header, an upper drum and rows of upright tubes communicably connecting said header and said drum, said tubes being arranged'with one row lining one side Wall of the chamber and another row lining the opposite side wall of the chamber, a hot coke container, and means for conveying said container into said chamber.

2. An installation for the dry cooling of incandescent coke and the like comprising achamber, a boiler comprising a lower header,

an upper drum, rows of upright boiler tubes communicably connecting said header and said drum, said tubes being arranged with one row lining one side Wall of the chamber, another row lining the opposite side wall and another row intermediate of said rows so as to divide the said chamber into two compartments, the intermediate row constitutmg a common wall for both compartments, coke containers, and means for conveying said containers into said compartments.

3. An installation for the dry cooling of incandescent coke and the like comprising a chamber, a boiler comprising a lower header, an upper drum, rows of upright boiler tubes communicably connecting said header and said drum, said rows being arranged so as to 7 provide water walls for said chamber and so as to divide said chamber into a plurality of compartments, and a plurality of hot coke containers adapted to be conveyed into said compartments.

In testimony whereof I have afiixed my signature.
